is img_hash a standalone module like opencv_world or a bug from cmake?
is img_hash a standalone module like opencv_world or a bug from cmake? . because when I make build file of opencv_worldxxx, img_hash doesn't merge with opencv_worldXXX.DLL, instead acts like another module opencv_img_hashXXX.DLL
that's why I don't include img_hash module from my opencv_worldXXX build.
unless someone will quid me a way to merge this 2 DLL(opencv_worldXXX.dll and opencv_img_hashXXX.dll) into 1
you can't, so don't. see below.
